2 Chronicles 29:33

Moreover Hezekiah the king and the princes commanded the Levites to sing praises to the LORD with the words of David, and of Asaph the seer. They sang praises with gladness, and they bowed their heads and worshiped.

Then Hezekiah answered, “Now you have consecrated yourselves to the LORD. Come near and bring sacrifices and thank offerings into the LORD’s house.” The assembly brought in sacrifices and thank offerings, and as many as were of a willing heart brought burnt offerings.

The number of the burnt offerings which the assembly brought was seventy bulls, one hundred rams, and two hundred lambs. All these were for a burnt offering to the LORD.

But the priests were too few, so that they could not skin all the burnt offerings. Therefore their brothers the Levites helped them until the work was ended, and until the priests had sanctified themselves, for the Levites were more upright in heart to sanctify themselves than the priests.

Also the burnt offerings were in abundance, with the fat of the peace offerings and with the drink offerings for every burnt offering. So the service of the LORD’s house was set in order.

Hezekiah and all the people rejoiced because of that which God had prepared for the people; for the thing was done suddenly.
